FLOAT-VALVE FO R WATER-TAN KS.

SPECIFICATION forming part of Letters Patent No. 665,795, dated. January 8, 1901.

Application filed July 2l, 1900. Serial No. 24,412. lNo model.)

To cir/ZZ whom t may con/cern:

Be it known that I, JOHN MORRISON, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented a new and useful Improvement. in Float-Valves for Water-Tanks, of which the following is a specification.

Myimproved valve is designed and adapted for automatically controlling the iow of water in reservoirs, tanks, cisterns, stock-watering troughs, dto. The valve is operated by a lever or two levers, as the case may be, and is connect-ed with a rocking or rotatable disk having a stop for limiting its movement. The valve engages a hooked post fixed on the valve-seat and is guided in its movement without appreciable friction. The details of construction and operation are as follows:

In the accompanying drawings, Figure l is a perspective view of a valve attachment. Fig. 2 is a perspective view of the invention in which two levers are applied. Fig. 3 is a perspective view of the valve proper and its' link.

The valve-seat A is provided with an internal screw-thread and in practice is screwed onto the inlet-pipe of a water-tank. The flatfaced valve proper, B, is provided with a facing of leather or other iiexible material to make a Water-tight joint when seated, as shown in Fig. 2.

The valve B has a tailpiece or shank b, which is provided with a lengthwise guideslot to receive a post O, cast integrally With the valve-seat The said post C has a hook or lateral projection at its upper end which prevents the valve becoming accidentally detached, yet allows its easy application and detachment as occasion requires. The post C is fiat or oblong in cross-section. It holds the valve B in due position or from lateral displacement on its seat. In other words, it allows the valve B to oscillate or have free movement, so as Lo adapt itself to the seat under all conditions of use and Wear.

The valve B is pivotally connected with a rotatable disk D by means of a link E. The said disk D is mounted on an axle d, journaled in the bifurcation of the vertical curved arm A of the seat A. The said axle d is thus supported directly over the center of the valve B. The disk D has a peripheral projection d', which when the disk is rotated for raising the valve, as shown in Fig. 1, strikes upon the base of the bifurcation of the arm A', and thus serves as a stop, controlling the movement or limiting the rotation of the disk D, and thereby the distance the valve can be raised. A lever F is shown bolted to the disk D and journaled on the axle d for use in operating the valve B. When a single lever F is used, a cord or float is attached to its free end for use in opening or closing the valve B, according as the lever is moved down or up.

When two levers F and F are used, as shown in Fig. 2, they are arranged practically diametrically opposite. In this case a float (not shown) is attached to lever F and closes the valve B, While a cord (not shown) is attached to lever F and passed up over the tank and runs ou a small pulley, so that by pulling such cord the valve B will open, the float on the other end being slightly immersed in this operation.

The valve is positive in opening and closing under high or low pressure, and there is no liability 0f its stickin'g by reason of friction.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a float-valve attachment for water-l tanks, the combination, With the valve-seat havinga fixed arm and ahooked post as specified, of the valve proper having a slot for receiving said post, a rotatable disk journaled in the aforesaid arm, a link pivotally connecting the valve and disk, the latter having a projection adapted to come in contact with the fixed arm when the valve is opened a predetermined distance, and a lever attached to the disk, as shown and described.

2. In a float-valve attachment for watertanks, the combination, with the valve-seat, having a fixed fiat post provid ed with a hook, and a bifurcated arm all constructed integrally, of the valve proper, having a slot adapted to receive and engage said post, a disk mounted rotatably in the bifurcatedarm, and having a peripheral projection that serves as a stop, a link connecting the valve and disk, and a lever secured to the disk for opening and closing the valve, as shown and described.

JOHN MORRISON.
